Setting Up Your Phone
•
near a powerful radio or television tower
•
when your AGPS antenna is covered (for example, by
your hand or other object) or facing the ground
•
when there are temperature extremes outside the
operating limits of the phone
Even where location information can be calculated in such
situations, it may take more time than usual, and your
location estimate may not be as accurate. Walking or
driving very slowly may also substantially reduce AGPS
performance.
Even where adequate signals from multiple satellites are
available, your AGPS feature will provide only an
approximate location, often within 150 feet (45 meters) but
sometimes much farther from your actual location.
The satellites used by your phone's AGPS feature are
controlled by the U.S. government and are subject to
changes implemented in accordance with the Department
of Defense AGPS user policy and the Federal Radio
Navigation Plan. These changes may affect the
performance of your phone's AGPS feature.
